Technical Field

[0001] This invention relates to the field of antennas, and in particular to an antenna device. Background Technology

[0002] With the development of wireless communication technology, fifth-generation mobile communication technology, also known as 5G, is becoming increasingly mature. Fifth-generation mobile communication technology typically uses signals with higher carrier frequencies. Therefore, the electromagnetic wave beam used to transmit 5G signals is narrower and has relatively weaker penetration than the electromagnetic wave beams of previous generations of mobile communication. This means that under the same conditions, the coverage area of ​​5G will be smaller. However, in practical applications, the use of mobile phones and other devices will increase, the amount of data exchange will grow, and the requirements for mobile communication technology will become more stringent. Therefore, improving the coverage area of ​​fifth-generation mobile communication technology is essential. Summary of the Invention

Detailed Implementation

[0039] The core of this invention is to provide an antenna device that can improve the range of receiving and transmitting antenna signals.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please refer to Figure 1 , Figure 1 This is a first structural schematic diagram of an antenna device provided by the present invention. The antenna device includes an antenna assembly, a rotating disk, a base 127, and at least two sets of rotating assemblies.

[0042] The antenna assembly is fixedly mounted on the rotating disk and is used to transmit and receive electromagnetic waves.

[0043] Each set of rotating components is mounted on the base 127. The drive end of each set of rotating components is rotatably connected to different positions of the rotating disk. Each set of rotating components independently controls its corresponding drive end to move in space, thereby driving the rotating disk to rotate in space.

[0044] Compared to previous generations of mobile communication technology, fifth-generation mobile communication technology uses a higher carrier frequency to transmit signals. Therefore, the electromagnetic wave beam used to transmit 5G signals is narrower than the carrier signal beam of previous generations of mobile communication technology, and its penetration ability is also worse. This means that under the same conditions, the coverage area of ​​fifth-generation mobile communication technology will be smaller.

[0045] To address the aforementioned technical problems, this invention provides an antenna device comprising an antenna assembly, a rotating disk for controlling the antenna assembly's rotation in space, a base 127, and at least two sets of rotating components. The rotating disk, base 127, and each set of rotating components correspond to a universal joint assembly 12. By controlling the rotation of different rotating components, the rotating disk can swing in multiple directions and angles, thereby enabling the antenna assembly to transmit and receive electromagnetic waves in various directions, thus improving the coverage range of the antenna device. Furthermore, the antenna device provided in this application is not limited to fifth-generation mobile communication technology; it can be applied to all scenarios where antenna assemblies are used to transmit and receive electromagnetic waves, and this application does not impose any particular limitation.

[0046] Specifically, the antenna assembly used for transmitting and receiving electromagnetic waves is fixedly mounted on the rotating disk. Therefore, when the rotating disk twists in space, the antenna assembly also twists accordingly, thus enabling the transmission and reception of electromagnetic waves from multiple directions and angles. Each set of rotating components is mounted on the base 127, and the drive end of each rotating component is rotatably connected to different positions on the rotating disk. Therefore, the twisting of the rotating disk is affected by the movement state of the drive ends of each set of rotating components. Furthermore, each set of rotating components independently controls the movement of its corresponding drive end in space. In other words, each rotating component is controlled independently. In practical applications, the drive end of one rotating component can be controlled to rotate while the drive ends of the remaining rotating components remain stationary, achieving adjustment of the antenna assembly in one direction. Alternatively, all rotating components can be controlled to rotate at the same speed in the same direction to achieve horizontal adjustment of the antenna assembly.

[0047] Please refer to Figure 1 , Figure 1 This is a first structural schematic diagram of an antenna device provided by the present invention. Figure 1Taking an antenna device comprising three rotating components—a first rotating component 124, a second rotating component 125, and a third rotating component 126—as an example, when the first and second rotating components 124 and 125 stop rotating, the third rotating component 126 causes the rotating disk to twist, achieving a directional swing. When the second and third rotating components 125 stop rotating, the first rotating component 124 causes the rotating disk to twist, achieving a directional swing. When the first and third rotating components 124 and 126 stop rotating, the second rotating component 125 causes the rotating disk to twist, achieving a directional swing, thus enabling individual adjustment in multiple directions and achieving a large angle and range of adjustment. When the first, second, and third rotating components 124, 125, and 126 rotate simultaneously, the rotating disk can be rotated horizontally, achieving a wide range of horizontal adjustment of the antenna component. In summary, by controlling the rotation of different rotating components, omnidirectional adjustment of the rotating disk and the antenna component is achieved.

[0048] In particular, the drive ends of each set of rotating components can be set at equal intervals along the outer wall of the rotating disk to ensure the control accuracy of the rotation direction of the antenna components.

[0049] In summary, this invention provides an antenna device including an antenna assembly, a rotating disk, a base 127, and at least two sets of rotating components. The antenna assembly is used to transmit and receive electromagnetic waves. The antenna assembly is fixedly mounted on the rotating disk, so when the rotating disk rotates, the antenna assembly also rotates, thereby enabling the antenna assembly to transmit and receive electromagnetic waves in different directions. Each set of rotating components is mounted on the base 127, and the drive end of each set of rotating components is rotatably connected to different positions on the rotating disk. Each set of rotating components independently controls its corresponding drive end to move in space, thereby causing the rotating disk to twist in space, thus improving the coverage range of the antenna assembly in receiving and transmitting electromagnetic waves.

[0050] Based on the above embodiments:

[0051] In one preferred embodiment, the rotating assembly includes a drive motor, a driving gear ring, a driven gear ring, a rotating component, and an extension component;

[0052] The output end of the drive motor is connected to the drive gear ring;

[0053] The rotating component is rotatably mounted on the base 127, and the rotating component is provided with a driven gear ring that meshes with the driving gear ring;

[0054] The first end of the extension is rotatably connected to the rotating part, and the other end is rotatably connected to a non-center part of the rotating disk.

[0055] This embodiment provides a specific implementation structure of the rotating assembly, which includes a drive motor, a driving gear ring, a driven gear ring, a rotating component, and an extension component, to achieve torsional control of the drive end connected to the rotating disk. Specifically, the drive motor outputs driving force and drives the driving gear ring connected to it to rotate. Since the driving gear ring meshes with the driven gear ring disposed on the rotating component, when the drive motor drives the driving gear ring to rotate, the driven gear ring will also rotate, thereby causing the extension component rotatably connected to the rotating component to rotate. Since the first end of the extension component (i.e., the drive end of the rotating assembly) is rotatably connected to the rotating component, and the other end is rotatably connected to a non-central location of the rotating disk, the extension component will drive the rotating disk to twist in space.

[0056] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 6 , Figure 2 This is a schematic diagram of a second structure of an antenna device provided by the present invention. Figure 3 This is a third structural schematic diagram of an antenna device provided by the present invention. Figure 4 This is a fourth structural schematic diagram of an antenna device provided by the present invention. Figure 6 This is a cross-sectional view of an antenna device provided by the present invention. Figures 2 to 6 Taking an antenna device comprising three rotating components as an example, the first rotating component 124 includes a first drive motor 1243, a first active gear ring 1242, a first driven gear ring 1241, a first rotating member 1247, and a first extension member 1244; the second rotating component 125 includes a second drive motor 1254, a second active gear ring 1255, a second driven gear ring 1251, a second rotating member 1257, and a second extension member 1253; and the third rotating component 126 includes a third drive motor 1262, a third active gear ring 1261, a third driven gear ring 1265, a third rotating member 1266, and a third extension member 1263.

[0057] In a preferred embodiment, the rotating parts of each group of rotating components are nested. In the nested state of the rotating parts, the driven gear rings in each group of rotating components are exposed to the corresponding rotating parts and are arranged sequentially along the central axis length direction of the rotating parts.

[0058] In practical applications, multiple independent rotating components can be set up individually. However, as the number of rotating components increases, the number of components used also increases, leading to higher costs. Furthermore, the area of ​​the base 127 needs to be increased, resulting in a larger overall size of the antenna device. Therefore, this embodiment provides an antenna device with nested rotating components, which can reduce the overall size of the antenna device and lower costs.

[0059] Specifically, to ensure that the driven gear ring can be driven to rotate by the driving gear ring when the drive motor rotates the driving gear ring, it is necessary to ensure that the driven gear rings of each set of rotating components are exposed outside the corresponding rotating parts in the nested configuration. This can be achieved by nesting the rotating parts of each set of rotating components. Simultaneously, to ensure that the driving and driven gear rings in each set of rotating components do not interfere with each other, in the nested configuration, the driven gear rings of each set of rotating components must be arranged sequentially along the central axis of the rotating parts.

[0060] Please refer to Figure 6 , Figure 6 This is a cross-sectional view of an antenna device provided by the present invention. Figure 6 Taking the antenna device comprising three sets of rotating components, with the rotating parts of each set of rotating components nested together as an example, Figure 6 The first rotating component 1247 of the first rotating assembly 124, the second rotating component 1257 of the second rotating assembly 125, and the third rotating component 1266 of the third rotating assembly 126 are nested together. The first rotating component 1247 and the second rotating component 1257 are both rotating sleeves, and the third rotating component 1266 is a rotating shaft. It is evident that nesting the rotating components of each group of rotating assemblies reduces the overall size of the antenna device and makes it more convenient to use.

[0061] In a preferred embodiment, the rotating assembly includes a first rotating assembly 124, a second rotating assembly 125, and a third rotating assembly 126;

[0062] The rotating component of the first rotating assembly 124 is a rotating shaft;

[0063] The rotating parts of the second rotating assembly 125 and the third rotating assembly 126 are both rotating sleeves. The rotating sleeve corresponding to the second rotating assembly 125 is nested outside the rotating shaft, and the rotating sleeve corresponding to the third rotating assembly 126 is nested outside the rotating sleeve corresponding to the second rotating assembly 125.

[0064] In this embodiment, the antenna device includes three rotating components: a first rotating component 124, a second rotating component 125, and a third rotating component 126. The rotating parts of these three rotating components are nested together. Specifically, the rotating part of the first rotating component 124 is a rotating shaft, located at the center of the rotating parts of each rotating component. The rotating parts of the second rotating component 125 and the third rotating component 126 are both rotating sleeves. To form a nested structure, the rotating sleeve corresponding to the second rotating component 125 is nested outside the rotating shaft, and the rotating sleeve corresponding to the third rotating component 126 is nested outside the rotating sleeve corresponding to the second rotating component 125.

[0065] In addition, in order to fix the first rotating component 124, a groove is provided on the base 127, and the bottom of the rotating shaft is rotatably disposed in the groove, making the overall structure of the antenna device more stable.

[0066] In a preferred embodiment, the upper part of the rotating component is provided with a mounting ring, which is connected to a connecting block. The connecting block extends radially outward from the rotating component and is connected to the extension component.

[0067] In this embodiment, in order to further prevent the rotating components from affecting each other during rotation, a mounting ring and a connecting block are provided between the rotating component and the extension component. The mounting ring is disposed on the rotating component and connected to the connecting block. Then, the connecting block extends radially outward from the rotating component to increase the rotation range of each rotating component.

[0068] For details, please refer to Figure 2 , Figure 3 and Figure 6 , Figure 2 This is a schematic diagram of a second structure of an antenna device provided by the present invention. Figure 3 This is a third structural schematic diagram of an antenna device provided by the present invention. Figure 6 The present invention provides a cross-sectional view of an antenna device, which includes a first rotating assembly 124, a second rotating assembly 125, and a third rotating assembly 126. The first rotating component 1247 of the first rotating assembly 124 has a first mounting ring 1246 on its upper part, which is connected to a first extension component 1244 via a first connecting block 1245. The second rotating component 1255 has a second mounting ring 1256 on its upper part, which is connected to a second extension component 1253 via a second connecting block 1252. The third rotating component 1266 of the third rotating assembly 126 has a third mounting ring 1267 on its upper part, which is connected to a third extension component 1263 via a third connecting block 1264.

[0069] In a preferred embodiment, the rotating disk includes a rotating disc 123, a straight rod 122, and a connecting seat 121;

[0070] The antenna assembly is fixedly mounted on the connector 121. The straight rod 122 is fixedly connected between the bottom of the connector 121 and the center of the rotating disk 123. The drive ends of each rotating assembly are rotatably connected to the non-center of the rotating disk 123.

[0071] Please refer to Figure 5 , Figure 5This is a front view of an antenna device provided by the present invention. The rotating disk specifically includes a rotating disk 123, a straight rod 122, and a connecting seat 121. The connecting seat 121 is used to fix the antenna assembly. The driving ends of each rotating assembly are rotatably connected to a non-central location of the rotating disk 123. Figure 5 The driving ends of each rotating component are rotatably connected to the edge of the rotating disk 123. The straight rod 122 is fixedly set at the bottom of the connecting seat 121 and the center of the rotating disk 123. When the driving ends of each rotating component drive the rotating disk 123 to rotate in space, the connecting seat 121 and the antenna component set on the connecting seat 121 will also rotate in space, thereby improving the coverage range of the antenna device for transmitting and receiving electromagnetic waves.

[0072] In a preferred embodiment, the antenna assembly includes a parasitic patch, a horizontally polarized radiating element 2, a vertically polarized radiating element 4, a vertically polarized radiating element feed point 5, and a signal transmission unit.

[0073] Parasitic patches are disposed on the horizontally polarized radiating element 2, and the parasitic patches are used to adjust the radiation characteristics of the antenna assembly;

[0074] The horizontally polarized radiation unit 2 is used to transmit and receive horizontally polarized electromagnetic wave signals;

[0075] The vertically polarized radiation unit feed point 5 is used to feed the power signal into the vertically polarized radiation unit 4. The vertically polarized radiation unit 4 is vertically arranged on the horizontally polarized radiation unit 2. The vertically polarized radiation unit 4 is used to transmit and receive vertically polarized electromagnetic wave signals.

[0076] The signal transmission unit is used to transmit electromagnetic wave signals to external devices.

[0077] The antenna device relies on antenna components to achieve the most basic function of transmitting and receiving electromagnetic waves. Antenna components include parasitic patches, horizontally polarized radiating elements 2, vertically polarized radiating elements 4, vertically polarized radiating element feed points 5, and signal transmission units. The antenna assembly may also include an 8x1 power splitting feed network 6, an extension cable assembly 7, a helical vertically polarized radiating element coaxial cable 8, and an 8x1 power splitting feed network coaxial cable 9. The 8x1 power splitting feed network 6 is used to evenly distribute the power signal to multiple output ports, thereby achieving multi-beam radiation; the extension cable assembly 7 is used to adjust the antenna's operating frequency and impedance matching; the helical vertically polarized radiating element coaxial cable 8 is used to transmit the antenna assembly's output signal to other devices; and the 8x1 power splitting feed network coaxial cable 9 is used to transmit the 8x1 power splitting feed network's output signal to other devices. In general, the functions of each component in the antenna assembly can be categorized as adjusting the antenna assembly's radiation characteristics, achieving polarized radiation in different directions, distributing power signals to different output ports, and adjusting the antenna assembly's operating frequency and impedance matching.

[0078] Please refer to the overall structure of the antenna assembly. Figure 7 , Figure 7 This is a schematic diagram of the structure of an antenna assembly in an antenna device provided by the present invention. Please refer to [reference needed] for the arrangement of the various parts included in the antenna assembly. Figure 8 and Figure 9 , Figure 8 This is a front view of an antenna assembly in an antenna device provided by the present invention. Figure 9 This is a top view of an antenna assembly in an antenna device provided by the present invention.

[0079] An extension line assembly 7 is fixedly connected to the top of the horizontally polarized radiation unit 2 at the inner side of the inner arc-shaped parasitic patch 3; an 8-to-1 power distribution network 6 is fixedly connected to the top of the extension line assembly 7; an 8-to-1 power distribution network coaxial cable 9 is fixedly connected to the 8-to-1 power distribution network 6; the 8-to-1 power distribution network coaxial cable 9 is installed on the horizontally polarized radiation unit 2; a spiral vertically polarized radiation unit coaxial cable 8 is fixedly connected to the middle of the horizontally polarized radiation unit 2; a vertically polarized radiation unit 4 is fixedly connected to the top of the spiral vertically polarized radiation unit coaxial cable 8; a vertically polarized radiation unit feed point 5 is fixedly connected to the lower conical part of the vertically polarized radiation unit 4; the spiral vertically polarized radiation unit coaxial cable 8 and the 8-to-1 power distribution network coaxial cable 9 are connected to an external power source.

[0080] The spiral vertically polarized radiating element 4 is the vertical polarization part of the antenna, and the entire dielectric substrate below the vertically polarized radiating element 4 is the horizontal polarization part of the antenna. The dielectric substrate can be an FR4 dielectric substrate with a dielectric constant of 4.4, a loss tangent of 0.02, and a thickness of 1 mm. The terminal of the 1-to-8 power splitting feed network 6 is the portion of the horizontal radiating dipole printed on the upper surface of the dielectric substrate, and the symmetrical portion of the horizontal radiating dipole is printed on the bottom surface of the dielectric substrate, which is connected to a circular ground plane. An inner arc-shaped parasitic patch is used to further widen the bandwidth, while an outer arc-shaped parasitic patch simultaneously increases gain and reduces gain variation in the direction of the horizontally polarized radiating element 2. Furthermore, the extension line assembly 7 helps reduce cross-polarization in the direction of the vertically polarized radiating element 4 because it reduces the current intensity of the vertically polarized radiating element 4 in the direction of the horizontally polarized radiating element 2 and increases the current intensity in the direction of the vertically polarized radiating element 4.

[0081] A single outer arc-shaped parasitic patch 1, in conjunction with an 8-to-1 power-sharing network 6, forms a reflector surface 10, which can improve the antenna's radiation characteristics, efficiency, and directivity. Specifically, their functions include the following aspects:

[0082] 1. Expanding antenna bandwidth: By using the outer arc parasitic patch 1 and the 1 to 8 power splitting network 6 together, the bandwidth of the antenna can be increased and it can operate on more frequency bands.

[0083] 2. Improve antenna gain and directivity: When the outer arc-shaped parasitic patch 1 and the 1 to 8 power distribution network 6 are used together, they can form a reflective surface 10, which concentrates the radiated energy of the antenna in a specified direction, thereby improving the antenna gain and directivity.

[0084] 3. Reduce antenna return loss: The combination of the outer arc-shaped parasitic patch 1 and the 1 to 8 power distribution network 6 can form a high impedance structure, which reduces the antenna return loss and improves the antenna efficiency.

[0085] 4. Improve antenna radiation pattern: By rationally designing the parameters and layout of the outer arc parasitic patch 1 and the 1 to 8 power distribution feed network 6, the antenna radiation pattern can be optimized, making it better suited to different application scenarios.

[0086] In summary, the combination of the outer arc-shaped parasitic patch 1 and the 1-to-8 power distribution feed network 6 can form a reflective surface 10, which has a positive impact on the performance and characteristics of the antenna and is an effective antenna design technique.

[0087] The inner arc-shaped parasitic patch 3 and the 1-to-8 power distribution feed network 6 work together to form a driven element 11, which can realize broadband tuning and directivity adjustment of the antenna. Specifically, their functions include the following aspects:

[0088] 1. Achieving broadband antenna tuning: The inner arc-shaped parasitic patch 3 can serve as the antenna tuning element, while the 1-to-8 power splitting feed network 6 can provide multiple input ports, enabling the antenna to operate on multiple frequency bands. The combination of the two enables broadband antenna tuning.

[0089] 2. Improve antenna directivity: By adjusting the coupling relationship between the inner arc-shaped parasitic patch 3 and the 1-to-8 power distribution network 6, the antenna directivity can be adjusted to meet the needs of different applications.

[0090] 3. Achieve antenna polarization adjustment: The coupling relationship between the inner arc-shaped parasitic patch 3 and the 1-to-8 power distribution network 6 can achieve antenna polarization adjustment, enabling the antenna to adapt to different signal polarization directions.

[0091] 4. Improve antenna efficiency: The cooperation between the inner arc-shaped parasitic patch 3 and the 1 to 8 power distribution network 6 can reduce the return loss of the antenna, thereby improving the antenna efficiency.

[0092] In summary, the combination of the inner arc-shaped parasitic patch 3 and the 1-to-8 power distribution network 6 can realize the antenna's functions such as broadband tuning, directivity adjustment, and polarization adjustment, which is an effective antenna design technology.

[0093] In a preferred embodiment, the parasitic patch includes an inner arc-shaped parasitic patch 3 and a pair of outer arc-shaped parasitic patches 1, and the inner arc-shaped parasitic patch 3 and the outer arc-shaped parasitic patch 1 are misaligned on the horizontally polarized radiation unit 2.

[0094] Please refer to Figure 7 , Figure 7 This is a schematic diagram of the antenna assembly in an antenna device provided by the present invention. In this embodiment, the parasitic patch of the antenna assembly includes an outer arc-shaped parasitic patch 1 and an inner arc-shaped parasitic patch 3 staggered on the horizontally polarized radiating element 2, and the outer arc-shaped parasitic patches 1 exist in pairs. By increasing the number and arrangement of the outer arc-shaped parasitic patches 1, the operating frequency band of the antenna can be extended, its bandwidth increased, the radiation characteristics of the antenna improved, and the profile height of the antenna reduced to suit height-restricted fields. Furthermore, multiple outer arc-shaped parasitic patches 1 can together form a high-impedance structure, thereby reducing the return loss of the antenna and improving the antenna efficiency.

[0095] Misaligning the outer arc-shaped parasitic patch 1 and the inner arc-shaped parasitic patch 3 increases the antenna's bandwidth, better meeting the needs of multi-band applications. When the inner and outer arc-shaped parasitic patches are misaligned, a high-impedance region is formed between them, reducing return loss and improving radiation efficiency. This misalignment also improves the antenna's directivity and beamwidth, making it more adaptable to various applications. Furthermore, the misalignment reduces the antenna's profile height, making it suitable for applications with height restrictions.
